Programmable Logic Controllers

Programmable Logic Controllers by Dag H. Hanssen delivers a clear and hands-on introduction to the essential role of PLCs in modern industrial and manufacturing automation. The book explains how these controllers manage a broad range of electromechanical tasks in challenging environments, making it an indispensable resource for anyone interested in industrial design and control systems. Adhering to the IEC 61131-3 standard, this guide takes a pragmatic approach to PLC programming using the widely recognized CoDeSys software tool. Through detailed examples based on real-world scenarios, readers are introduced to the principles of Boolean algebra, flowcharts, sequence diagrams, and state diagrams, which collectively support a structured and efficient programming methodology. Ideal for beginners as well as experienced practitioners, the book outlines clear strategies for solving control problems, developing robust code, and documenting programming processes. It also covers practical aspects such as integrating sensors, managing signals, and ensuring the reliability of various I/O devices, making it a valuable asset for anyone looking to enhance their skills in electronic design automation.
